Spiny buttercup (Ranunculus muricatus) is a non-native plant, that is fairly common, especially in wet areas such as meadows. We also find it in crops, including orchards, pastures, and cereal grain fields. It's both an annual and perennial plant that blooms from March to May, with seed pods that are large and prickly. Though it's pretty with the bright yellow flowers, don't be fooled, as it has a dark side, so should be controlled.
First, according to Dr. Birgit Puschner, UC Davis Vet Med Toxicologist, all buttercups contain ranunculin, though there are differences in species in terms of toxin levels. In pastures, because the plant is bitter, animals simply eat around it. But if ingesting the fresh plant, they...

Way back in the early 2000s (we think…there's no date on it!) the San Benito County Weed Management Area developed a great weed guide for our area called Selected Invasive Weeds of San Benito County: A Field Identification Guide. It contains twenty five of the most common weed species in the county. For each weed there is information about what it looks like, where it's from, where you can expect to find it, and a brief paragraph about how it can be controlled. The guide is handy because it's small enough to stick in your back pocket or put on the passenger seat of your truck to take into the field with you. Unfortunately, there are only a handful of copies left and people still need the information. But, don't worry! I...

Graduate student, post-doc, and technician positions available to investigate the genetics of invasiveness and herbicide resistance in aquatic plants
Description: Assist with a funded research project combining molecular genetics and field/greenhouse studies to investigate the genetic basis of growth and herbicide response of invasive aquatic plants. Field work will take place in Michigan inland lakes, and the position will be held at Montana State University. The key issue addressed is how best to manage genetically diverse aquatic plants, now that we know that different genotypes can exhibit vastly different growth and herbicide sensitivity. This research will...
